Using the Square Root Property to solve the quadratic equation we have
c = 5,-17.
<h3>What is
Square Root Property?</h3>
Simply put, the square root property asserts that if one side of an equation is a perfect square and the other is a number, then we can solve the problem by taking the square root of both sides and then adding a plus or minus sign to the side containing the number.
Generally, the quadratic equation is mathematically given as
c2+12c+36 = 121
Therefore
(c+6)2 = (11)2
(c+6) = 11 or (c+6) = -11
c = 11-6
Hence, the roots of the equation are
c = 5 or c= -17
In conclusion, the solution for the quadratic equation is
c = 5,-17.

Answer:
Step-by-step explanation:
Try this solution:
1. note, that 4-5=-1; -1-5=-6; -6-5=-11; -11-5=-16, etc.
The suggested sequence is arithmetic, where a₁=4; d=-5.
2. using a₁ and d it is possible to calculate a₁₄=a₁+d(n-1)=a₁-5(14-1)=4-5*13=4-65=-61.
